Kurt.energy enters new markets with safe Sodium-ion cells and Energy Storage solutions.
At Kurt.energy, a division of Altreonic, safety has always been one of our main concerns when selecting battery cells. It is a pleasure to announce we now offer leading-edge sodium-ion cells and energy storage solutions in an exclusive agreement with the manufacturer.
Sodium-ion battery cells are a novel and sustainable alternative for Lithium-ion battery cells (especially LFP). Rather than being based on Lithium (Li), these battery cells use Sodium (Na) as the active metal compound. Sodium (or Natrium) is a basic element. It is abundant and found in table salt and the salt in the sea (NaCl or Sodium Chloride).
The Sodium-ion (or Na-ion) chemistry Kurt.energy selected has many benefits:
-
- No Lithium (Li) or other problematic materials like Nickel (Ni) and Cobalt (Co) are used
- Sodium is much more abundant and doesn’t require problematic mining
- Can operate from -40 to +60 up to +80°C (cell-dependent)
- Charging from -10 to +60°C (cell-dependent)
- 3000 to 6000 charge/discharge cycles (cell-dependent)
- Power: can reach 3C up to 20C (cell-dependent)
- Energy densities up to 130 Wh/kg (cell-dependent)
- Ultra-safe: no risk of fire (yes, we did hard short-circuit and overcharging tests)
- Compatible with existing battery assembly methods
- Easy recycling
- More Cost-efficient than Lithium-ion cells.
Sodium-ion cells have very few drawbacks. Currently, they have a slightly lower energy density than LFP cells, but they have a wider temperature range and can provide more power. The DoD is higher and they can even discharge to 0V. They need an adapted charger when operating at extreme temperatures, but can charge from any standard charger when used at typical moderate temperatures.
All in all, Sodium-ion batteries are a significant step forward towards sustainable electric energy. While the primary use is for Energy Storage, they offer a safe and sustainable alternative for light electric vehicles as well.
Below, are some of the cells and battery systems being prepared for the market. This range consists of small cylindrical cells (1.3Ah), high-capacity/high-power prismatic cells (160 Ah), portable power stations, low-voltage stackable battery/inverters from 3.5 kWh, and battery/inverter systems up to 300 kWh.
Note, Kurt.energy only sells B2B. Wholesale partners and value-adding system suppliers/installers are welcome (Europe and Africa). Downloads:
